High Voltage Scanner Card
Information
The Model 7054 is a high voltage scanner card that switches signal levels up to 1000V, 0.5A or 10VA peak (10mA at 1000V) for resistive loads only. Each of the 10 channels on the card consists of a single-pole, Form A (normally open) relay with a common guard connection and a fused input. The output connection and the input connections have quick disconnect screw terminals with a maximum allowable wire size of No. 18 AWG. Single-pole switching is done in less than 20msec exclusive of the mainframe, and the specified contact life is 10s closures with cold switching and 106 closures at maximum signal levels. Contact resistance is less than lfi. The relay drive current is 50mA/relay. The Model 7054 is field installable in an appropriate Keithley scanner mainframe (e.g. model 705 or model 706). With the isolation between each channel being greater than 1012fl and less than lOpF, each channel is well insulated from cross channel noise and interference.
